Essential Blogging

Chapter 7: Advanced Radio UserLand

Radio UserLand (Radio) is a sophisticated, rich product. Radio goes far beyond simple
blogging, with powerful features such as macros, object databases, outliners, a built-in
web server, a full development environment, a scripting language, support for the Blogger
API, and the ability to build your own web services. In this chapter, we start with a
description of the products related to Radio: UserLand Frontier and Manila. After that,
we continue with Radio techniques such as shortcuts and categories and then move into
more advanced topics such as macros and UserTalk.
